IMPROVEMENT IN ROTARY FORCE-PUMPS.

Specification forming par-t of Letters Patent No. 170,343, dated November 23, 1875 application tiled June 10, 1875.

To all whom it may concern Be it known that I, AsA GARLIN, of Stones Prairie, county of Barry and State of Missouri, have invented a new and useful Improvement in Submerged Rotary Pumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings forming a part of this specification, in which- Figure l represents a side elevation of the pump-cylinder, Fig. 2, a perspective view of the interior of the saine; Fig. 3, a longitudinal vertical section of the pump cylinder and driving-wheel, and Fig. 4, a side view of the tube, discharge-nozzle, and driving-gear.

Pumps of the class to which my invention relates, so far as I am aware, have been open to many objections, owing to the complicacy ot' the operating parts, rendering the same liable to get out of repair by continued use. It is also well-known that rotarypumps in which the Water is raised by suction frequently require priming.77 By submerging the pump the necessity for such operation is entirely removed, as the pump is always inv order for action.

VThe object of my invention, therefore, is to specially construct a pump that will admit of its being submerged in the water, and entirely dispensing with the additional construction or change requisite to make the said pump lift by suction, making a much siml pointed out in the claim.

In the drawings, A represents the outer cylinder of the pump, formed with an opening, G, at its side, through which the water passes into the cylinder, and'which is protected by i a metal wire-gauze covering or plate, a. Upon the interior ofthe cylinder'A is a cam-projection, e, which approaches nearer the center as it extends to the offset t'. The drive-wheel C, 'as represented in Fig. 3, is formed with two vertical chambers, arranged opposite each other, and communicating with water passages f, the same being controlled by checkvalves b. These chambers receive looselyfitting valves N, formed with inclined recessss h, two in each valve, and arranged one above the other. 'Ihese valves are extended from the bottom of the Wheel C to the rim S, and enter about halfway through the same. rIhe drive-wheel C is held in place within the cylinder A by a lid, B, secured thereto by suitable bolts c, which pass down and screw to the annular flange d of the cylinder. lhe lid B, at its center, is formed with a screw-flange, upon which is secured a suitable stuffing-box, O. The tube D, through which the water passes after leaving passages f, is secured to the drive-Wheel C by connecting the same with the screw-nipple g, forming a communication with the opening in the tube and the passages f. At the upper end of the tube D is loosely connected, by a bush-coupling, a dischargenozzle, K, so that the position of the nozzle will not be affected by the rotation of the tube D, motion being imparted to the latter by aid of a bevel-gear wheel, E, rigidly connected to the tube, and meshing with the teeth in a bevel-gear wheel, F, secured to the end of a driving shaft,l j, operated by any suitable power.

To understand the operation of my in vention l,will require but a brief explanation. Motion being given to the shaft j, carrying the gear-wheel F, communicates a rotary motion to the tube D, through the lmedium of the gear-wheel E, the driving-Wheel C also being rotated, which, with the aid of springs,

throws out the valves N from the center ofthe wheel, trapping the Water thatenters the opening G, into the space between the wheel and the cylinder A. The drive-Wheel C fits close to the abutment t', thereby causing the water before the valves N to enter the recesses hy in the same, from whence it passes into the passages f, and through the opening in the tube D, out through the nozzle K, the check-valves b preventing the return ot' the Water into the cylinder A, but allowing its escape into the tube D. The valves N are forced to the ceuter of Wheel C WhileV passing the continuation of"` the cam e or o'set 'L'. The rim S of the drive-Wheel G is perfectly cylindrical, and suffciently large in diameter to snugly fit the interior of the cylinder A above the cam e.

Having now fully described my invention, what I claim as new, and desire. to secure by Letters Patent, is-

l. The submerged rotary pump, as described, consisting of the `cylinder A, provided with cam e and water-inlet G in lche side thereof,.

and the Wheel C formed with Water-passages f, and carrying valves N, with recesses h, and

check-valves b, substantially as and forthe purpose set forth.

2. In combination with'cylinder the` i drive-wheel C, provided with recessed valves AN,passagesf, check-valves b, discharge-tube D. and nozzle K, connected thereto in aimanner that will admit of the rotation ofthe tube i Without affecting the position of the nozzle,

substantially as and. for the purpose speciiied.`
